External services
This plugin relies on the sevDesk REST API, a third-party accounting and invoicing service, to create invoices and manage contacts.
What is the sevDesk REST API?
sevDesk is a German cloud accounting and invoicing platform. This plugin uses their official REST API to:

Authenticate with a personal API token
Create and update contacts (customers)
Create invoices (draft or finalized via sendBy)
Retrieve invoice data and download PDF documents
Read SevUser (connection test)
(PRO) Create credit notes, send e-invoice flags, bookAmount (mark as paid), and related document options

API base: https://my.sevdesk.de/api/v1/
What data is sent and when?
The plugin sends data to the sevDesk REST API (https://my.sevdesk.de/api/v1/) in these situations:
When you click “Create Invoice” or when automatic invoice generation is triggered (PRO version):

Customer billing information: name, company, USt-IdNr / VAT ID, email, phone, billing address (street, city, postal code, country)
Order information: line items (names, quantities, net/gross amounts, tax rates), shipping and fees, voucher date, optional headText/footText (PRO)

When the plugin connects to sevDesk (settings page or as needed):

Your sevDesk API token (Authorization header, raw token)
Requests to retrieve SevUser, contacts, invoices, check accounts, and PDF files

No data is sent automatically without your action (FREE). The free plugin communicates with sevDesk when:

You manually create an invoice from the order screen
You click Test Connection on the settings page
You download an invoice PDF (admin or My Account)

With PRO automation enabled, invoices/credit notes may also be created when order status changes or refunds are issued, and invoices may be booked as paid when the order reaches processing/completed, according to your settings.
